Exploratory Factor Analysis and Confirmatory Factor Analysis are two of the most common data reduction techniques that allow researchers to create scales from responses on the initial items.Advanced statistical methods include the opportunity to discover previously unidentified or unexpected relationships between items or constructs.It also may allow for the development of subtle items that prevent test takers from knowing what is being measured and may represent the actual structure of a construct better than a pre-developed theory.

Common formats for these norms include percentile ranks, z scores, sten scores, and other forms of standardised scores.

Test development can proceed on theoretical or statistical grounds.

There are three commonly used general strategies: Inductive, Deductive, and Empirical.

Work by numerous other researchers over the proceeding decades produced additional support for the five factor structure.

Mc Crae and Costa operationalized these five factors of personality into the measure known as the NEO-PI, one of the most well used versions of the five factor model.
